That is a totally valid point. A lot of the terms being thrown around mean slightly different things to different people. Is profit taking money management or trading strategy? Is a 5/8 EMA crossover strategy essentially the ‘same’ strategy as an 8/13 SMA crossover strategy, or should they be viewed as different strategies altogether? Different traders will have different answers.
Clearly, it is possible to sit down and create a strategy so bad, so unrealistic, that no amount of money management can save it. However, the internet is full of strategies (using that word in a very broad sense - crossover strategies, RSI strategies, etc) that are capable of being profitable with the right money management and psychology.
New traders (and we’ve all been there) cannot see this, because the chances of a new trader having both good money management and the right psychology for whatever system they happen to pick up are essentially zero. However, just like a fish can’t see water, new traders cannot see the psychology and money management decisions that they are making that destroy an otherwise profitable system. So they hop from system to system, or look for that ‘holy grail’ combination of indicators, never actually working on the real problem.
It typically takes a great deal of pain before we finally accept that the problem is actually ourselves, and begin the task of fixing our mistakes. Most traders never make that leap.
